' a This ,inventionrelates to-irnprov'ements' in I apparatus" for operating, doors and isdirect edmqre 1 ing andgclosingthe swinglng doors of garages 6 and the like. i r

: Theprincipal object bfi the r inventionfis the provision of apparatus which is adapted to be-operated at location remote fromthe Y doors. f For instance, the driver o'fa vehicle entering or leaving agara-gemay," without leaving the vehicle," grasp certain operating [devices and "cause the apparatus either open or close a door or doors.

I I cable The-innerends of the links are pivoted at18 I ongitudinal operating bar 20. The inner end ofjbai' 20 is pivotally at 21 to one end of a knuckle bar 22,'the other endof whichis pivotally connected to a'bracket 24 fixed on the rear wall '4 of, the building. 1 i v, I "l he bars are so proportioned and connected that astheymove from the full line to the, dotted line position i from their closed to the r open position. As they move ina reverse direction, they function to close thedoorsg 1 I A support 26 fixed tothe, garage structure has a hook 28 pivotedthereto, the lower end of whichgis adapted to engage thepivot 21' so as tofhold the bars in their upperposition. Aftension spring 30 connected between the upper end'of hook 28 and a'pin 3201. said support urges the hook into the latching en} ga ement with the pivot, as shown. j I weight 34'on one of the barssuchas 20 is provided to cause the bars to descend when e pivot is released by thehook. v I housing 36 located outside thebuilding 38 pivote'd therein and receives one end of a conduit 40 which extends into th'ebuildin'g; I I y 8 A cable 42 connectedat one end to the weight 34 or to 0 18 of the bars is guided over r- 7 pulleys 44"an'd 46*and' extends through con- 30 I is connected to the lower end of'lever 38.2 v I 1.

pulling it thehookis swung to release the pivot mem-. ber 21 and the Weight, causes the bars to descend, to spreadthe 'links'and openthe doors. With' the doors closed as a vehicle is brought to a stop adjacent" the housing, an operator may reach for the free end 56 of,

assisted by the weight descend to force the doors to an open position.

As avehicle is driven out of the garage an operatormay, when the vehicle is brought to a stop position adjacent the housing, grasp the lever and swing it soas to elevate the bars and close the doors in which position they are held by thehook which engages the plvot pin 21. r

I I It maybe desirable to attach auxiliarypa- H ble operating members to thegcabler, at po nts near the corner of the building. These may i a be grasped by a person at that place withoutthe necessityof going over first named angular building a'n'da Jacent a rear part of said-building with ap paratus for operating said doors compris 'ing, links connected .at outer ends to said 7 3d o ent arear partlof to the housing. It will be observed that the apparatus 0peratesbetween acontracted and expanded position and functions 1n thenature of a wedge to move the doors outwardly.
